(1) Consider three different raster systems with resolutions of 640 by 480, 1280 by 1024, and 2560 by 2048. What size frame buffer (in bytes) is needed for each of these systems to store 12 bits per pixel? How much storage is required for each system if 24 bits per pixel are to be stored? (2) Suppose an RGB raster system is to be designed using an 8 inch by 10 inch screen with a resolution of 100 pixels per inch in each direction. If we want to store 6 bits per pixel in the frame buffer, how much storage (in bytes) do we need for the frame buffer? (3) How long would it take to load a 640 by 480 frame buffer with 12 bits per pixel, if 105 bits can be transferred per second? How much would it take to load a 24 bit per pixel frame buffer with a resolution of 1280 by 1024 using this same transfer rate? (4) Suppose a computer with 32 bits per word and a transfer of 1 mip (one million instruction per second). How long would it take to fill the frame buffer of a 300dpi (dot per inch) laser printer with a page size of 8 inches by 11 inches? (5) Consider two raster systems with resolutions of 640 by 480, and 1280 by 1024. How much pixels could be accessed per second in each of these systems by a display controller that refreshes the screen at a rate of 60 frames per second? What is access time per pixel in each system? (6) Assuming a transfer rate of 0.1 MB/sec. How much time would be necessary to load pixmap with resolution (a) 512*512*1, (b) 1024*1280*1 //17% retrace per frame(7) Compute the access time per pixel for systems with resolution (a) 640*480 (b)
